gpt-4o is dying today and i’m actually kind of relieved?
https://www.reddit.com/r/programming/comments/1r3kirg/gpt4o_is_dying_today_and_im_actually_kind_of/
<!-- SC_OFF -->honestly watching the meltdown over openai retiring 4o today is wild. like yeah, it was the reliable workhorse for mern stack boilerplate and fixing my broken docker configs at 2am, but is it just me or was it starting to feel... mid? i’ve been moving my workflow over to agentic tools and things like claude code anyway. it feels like we’re finally moving past the "chatbot" era and into actual autonomous dev tools. 4o served its purpose but i'm ready for the next thing to just handle the organization-service logic so i can actually go outside for once. are you guys actually mass-unsubscribing or are we just being dramatic for the sake of it? <!-- SC_ON --> submitted by /u/Pansota03033288667 (https://www.reddit.com/user/Pansota03033288667)

Profiling and Fixing RocksDB Ingestion: 23× Faster on 1M Rows
https://www.reddit.com/r/programming/comments/1r2stkm/profiling_and_fixing_rocksdb_ingestion_23_faster/
<!-- SC_OFF -->We were loading a 1M row (650MB, 120 columns) ClickBench subset into our RocksDB-backed engine and it took ~180 seconds. That felt… wrong. After profiling with perf and flamegraphs we found a mix of death-by-a-thousand-cuts issues: Using Transaction::Put for bulk loads (lots of locking + sorting overhead) Filter + compression work that would be redone during compaction anyway sscanf in a hot CSV parsing path Byte-by-byte string appends Virtual calls and atomic status checks inside SstFileWriter Hidden string copies per column per row Maybe our findings and fixes are helpful for others using RocksDB as a storage engine.

Go - Unit & Integration Testing
https://www.reddit.com/r/programming/comments/1r297wt/go_unit_integration_testing/
<!-- SC_OFF -->Hi. I wanted to make a detailed guide about how to unit/integration test in go, I felt as if there aren’t enough guides that help break this down, and explain it thoroughly. Hopefully. this article achieves that. While writing the article, I decided to take the mindset of someone coming straight from writing go code. Might not understand docker, or the libraries involved in testing go code. What is covered in this article? Why do we test? Main methodology behind software testing What is an interface? What is dependancy Injection? How to install required dependancies Example Project Unit testing What is a container? Integration testing This took an unbelievable amount of time to write so, I hope this helps somebody! If anyone has any feedback, please feel free to leave a comment. <!-- SC_ON --> submitted by /u/CallumMVS- (https://www.reddit.com/user/CallumMVS-)

Microsoft Discontinues Polyglot Notebooks (C# Interactive)
https://www.reddit.com/r/programming/comments/1r28bdg/microsoft_discontinues_polyglot_notebooks_c/
<!-- SC_OFF -->I've just been notified by the maintainers of Polyglot Notebooks (C# Interactive) that it is also being discontinued.
dotnet/interactive#4071 (comment) (https://github.com/dotnet/interactive/issues/4071#issuecomment-3886574191) Polyglot is still listed as the recommended tool for analysts migrating their SQL notebooks away from ADS.
https://learn.microsoft.com/en-us/sql/tools/whats-happening-azure-data-studio?view=sql-server-ver17&tabs=analyst EDIT: They removed the reference (https://github.com/MicrosoftDocs/sql-docs/commit/3afe962f6b0232bdc94fd9f6355a5adb818d3e29#diff-3fab63d78311dfc3b0f0f6a739cfa29e918820bb990b4ce012dc64d589b92788L43) The suggestion here is to convert your notebooks to file based apps. The primary benefit of SQL notebooks was that you didn't have to be a developer to use them.
dotnet/interactive#4163 (https://github.com/dotnet/interactive/issues/4163) I spent a week putting together a PR to better integrate Polyglot with vscode-mssql. This type of behaviour is so bad for OSS. <!-- SC_ON --> submitted by /u/WhitelabelDnB (https://www.reddit.com/user/WhitelabelDnB)
